A major US cruise port will be “shore power ready” by 2023.

Miami-Dade County, in partnership with Florida Power and Light Company (FPL), Carnival Cruise Line (CCL), and Royal Caribbean Group (RCG), said shore power will be available at PortMiami by autumn 2023.
"Our efforts to make PortMiami 'shore power ready' are moving full steam ahead thanks to the incredible work of the PortMiami team, FPL, and the commitment of Carnival Cruise Line and Royal Caribbean Group," said Miami-Dade County Mayor, Daniella Levine Cava. "Our goal is to continue ensuring PortMiami is a leader in sustainability and to shape a more resilient cruise industry that prioritizes the protection of our environment.”
Work underway
Cruise Terminal F, currently undergoing a significant expansion for CCL, and RCG’s Cruise Terminal A will be the first facilities with shore power capability at PortMiami. Both lines have committed to retrofitting vessels within their fleet to utilise this power source at the port.
The programme is being implemented in phases. Phase one at Cruise Terminals A and F will transform the power levels at the port from the electrical grid to cable management systems for the heavy plugs and outlets on the vessels. This system requires each party to implement improvements on the electrical grid and supply lines, shoreside equipment on the pier, and shore-to-ship connection on the cruise ship.
Phase two involves PortMiami working with other cruise line partners to ensure that their designated berths also have shore power connectivity.
